Also what is a namespace?

A namespace describes where variables and modules reside. Each scope is its own namespace. I could be wrong but I believe even modules are their own namespace.

Oh that makes sense and by scope are you referring to global variables or variables inside a function, etc.?

#6

Yes. Each block has its own scope.
